Sound problem.

Hi all,

I've got a little problem someone may be able to help me with.

Messing about with the audio side of things is not something I'm familiar with so I'm looking for a little advice.

I've recently recorded a set of speeches with two cameras and two microphones...the problem is one microphone started to play up a bit and I was getting the occasional "whoosh" every so often. Unfortunately, this was the microphone that was in front of the main speaker and the other was a short way away but it did pick up the sound okay if a bit distant!

What would be the best way to "mix" this sound together that would make it presentable? The interference comes and goes throughout the 20 minute presentation with some bits worse that others and I was just wondering how to go about taking 20 seconds from one microphone, 30 from the other and so on for the full 20 minutes.

Here's hoping somebody can come up with a simple solution.

Thanks in advance,

Parsman.

Parsman What I would do is use the video from the camera with the good audio and use the video with the offending audio as B roll. Use the split and insert Method to mix the scenes from the 2 videos. Find a common point on each video, a body movement, a clap any thing wher you can be sure they are pretty close and you can sync them at th is point. This way when you use the video from the other camera the lips will be in sync. I hope this helps. Bob...

Hi Flvideo,

Thanks for your suggestion...I've already mixed the film using the second source audio but ideally, I'd like to use as much of the "faulty" audio as possible, so I'm planning to sort of mix the two together but I'm just wondering what's the best way to go about this?

Hi Parsman

What I would do is to split the faulty audio track up in good and bad pieces by just scrolling trough but always use the use option not drop it.
This way it is easier to match the audio up when inserting the audio on a spare audio track.
Then you drop them all in an audio track one after one so there are no break ups- done that don't render it yet but use the correction tool to either
mute the original audio track or the other track you might want to put some fades in between them to not make the switch seem to harsh
or not totally mute the faulty scene and keep it there for a little bit.

Please note; Make sure the faulty audio track matches the original before splitting as it would a big waste of time if it doesn't.

Hope this helps good luck.

Thanks Jeanton,

I'll do exactly that tommorow. I had planned on maybe mixing a new soundtrack by running through the bad one and noting the times of the faults then using a mixer to fade between the two but I think your idea is better. I just hope that the fades between the good and bad tracks are not too obvious.

Thanks again,

Parsman.

Hi Parsman

If you run it through a mixer you will be most of the time to late to switch and this way if you use the wave sound thingy you will see where it starts and ends.
Also adjust the levels from a couple render it and watch it back listen if it sounds right to you maybe you have to adjust the level of the original maybe not
then write the levels of adjustment down and continue with the rest so you don't have to adjust them all later on.
Small fades 6 frames should't be to obvious play with that too.
